Renewed October 14 Claims.

This invention pertains to a garment or ironing press having coacting press jaws consisting of a head which is swingable upwardly and rearwardly of the other and fixed jaw or buck so that a clear view of the work upon the fixed jaw is obtainable. The invention relates particularly to the operating mechanism by which the swingable jaw-is moved away from the other jaw as well as to the particular frame construction for supporting such mechanism.

It is an object of the invention to construct a garment or ironing press in which the movable jaw or head is raised and lowered substantially vertically to and from the buck or fixed jaw in order to obtain jaw compression without relative sliding motion between the jaws and in which the movable jaw is swingable rearwardly to clear the work with novel operating mechanism to produce the movement.

Another object of the invention is to produce a novel construction of mounting for a jaw-carrying member which carries the movable jaw or head so that the member will have more rigid and improved support upon the press frame.

-Another object is to devise a new and novel operating mechanism for a garment or ironing press. I

Other objects of the invention will be more apparent from the following description, taken in connection with he accompanying drawings, in which:

Figure 5 is a section taken on line 55 of Figure l showing the position of the operating mechanism and jaw-carryingmember in fullopen press position.

Figure 6 is a section taken on line 6-6 of Figure 4 showing details of the frame construction and the manner in which the jaw-carrying member is mounted thereupon, so that the head carried by the member is swingable towards and away from the fixed jaw or buck.

The garment or ironing press of the invention includes a stationary jaw or buck and a movable jaw or head which comprise the coacting press jaws. The movable head is carried upon a jawcarrying member which is given a swinging movethe operator to obtain a clear vision of the Work upon the buck without interference from the head. The operating mechanism by which the movable head is swung away from the stationary buck comprises the principal feature of the invention, although details of the frame supporting the press and the mechanism for supporting the jaw-carrying member constitute some of the more detailed features of the invention.

The press is provided with a frame I0 carrying a pedestal II to support a stationary jaw or buck The movable jaw or head I3 is mounted upon a jaw-carrying member I4 which member is given a swinging movement in order to carry the movable jaw or head I3 over the stationary jaw or buck I2 and subsequently give it a vertical movement to obtain jaw compression. The reverse of these movements occurs upon opening of the press. The buck I2 and movable head I3 comprise the coacting jaws of the press.

The jaw-carrying member I4 is provided with a pair of guide pins I8 carrying rollers I9 which engage within a slot in each side of the frame I0. The guide pins I8 with their rollers I9 working in the slots 20 provide means for guiding the jaw-carrying member I4 and preferably for the lower end thereof and assist in controlling 01 directing the movement of the head I3 and jawcarrying member I4. The jaw-carrying member also pivots about the guide pins I8 as well as being guided thereby. Any other form or type of guide means is contemplated by the invention such as a radius link construction which is equivalent in function .and operation to the preferred construction described herein.

The jaw-carrying member I4 carries a pair of bearings 23 which provide compound motion pivots 24 in axial alignment for the jaw-carrying member which are spaced from the guide pivots formed by the guide pins I 8. The compound motion .pivots 24 are preferably positioned in the central part of the jaw-carrying member. Each of the compound motion pivots 24 is mounted in its bearing 23 so that each end projects beyond its respective bearing thereby forming outer ends which project outside of the jaw-carrying member l4 and inner ends which project towards each other within the jaw-carrying member.

Radius links 25 are secured to the outer end of each of the pivots 24 and are pivotally mounted in the frame it) upon a frame pivot 26. The inner ends of each of the compound motion pivots 24 are secured to radius links 21 which are pivotally carried upon a frame pivot 28 mounted in a central bearing 29, shown more clearly in Figure 6, the bearing being carried by a supporting flange 38 extending outwardly from the side and top of the frame iii to bring the bearing 29 into alignment with the pivots 26. The frame pivots 26 and 28 are in direct alignment and for all purposes function as one and the same pivot for the radius links. The radius links 25 and 21 with the compound motion pivots 24 and the frame pivots 25 and 28 comprise radius link means which pivotally carry the jaw-carrying member 14. A simpler construction for the radius link means is suitable but does not afford the rigidity and smoothness of operation that is obtained by the radius link means described herein. i

The jaw-carrying member 54 carries a pair of spaced flanges 3| which give the jaw-carrying member rigidity and enable it to pass between the radius links 25 and 21 which are spaced apart to permit this construction. There is therefore a radius link on each side of each bearing 23 or upon each end of each compound motion pivot 24 which reduces wobble in the press and results in a smooth operating press and assures the head .and buck coming intoproper pressing alignment.

'The jaw-carrying member M has therefore spaced pivots comprising the guide pivots or pins 18 and the compound motion pivots 24, and upon the latter are mounted the links 25 and 21 which form radius link means for supporting or carrying the jaw-carrying member and swinging it and the head to open and close the press. The guide pivot 18 spaced from the compound motion pivots 24 of the jaw-carrying member 84 is preferably guided in its movement by the groove 28 which may be of any desired construction and the curve taken by the grooves 23 is designed to enable'the head .to have a substantially vertical movement during the approach and removal of the head from the .buck or during jaw compression. In addition, the grooves 20 cooperate with the radius link means to give the head l3 a rapid rearward and forward movement when opening and closing the press.

The radius links 21 have an extension or actuating means which is shown as a cam arm 35 in which a cam groove or slot 38 is provided consisting of a rapid-movement or high-speed portion 31 and a compression or pressure portion 38 disposed at an angle to the high-speed portion 31. The high-speed portion 31 is in fact and in effect a shoulder which is engaged by the force applying means and is moved at the same rate of speed or substantially at the same rate of speed as the power means. It is pointed out here also that the high-speed portion 37 of the cam slot 316 is also nearer to the frame pivot 28 upon which'the cam arm is pivotally mounted and the compression or pressure portion 38 is more distant from the pivot 28 than the rapid-movement portion 31. The purpose of the angular relation of the two portions 31 and 38 of the cam groove 36. the effect of their distance from the frame cam roller or power means.

pivot 28 and the manner in which they function will be described in greater detail hereinafter. The cam groove or slot 36 comprises cam means which is connected to the radius link means, although in its preferred form the cam means is integral with the radius link means. Similarly, a pair of cam grooves 36 is shown to improve the smoothness and uniformity of operation, but it is clear that at least one such cam or actuating means will operate the press.

A cam roller 4! or force applying means engages within the cam slot 33 and is carried upon a roller shaft 42 mounted in a cross head 43. The cam means with its slot 38 in receiving the cam roller 4| is also termed a force receiving means since the operating face of the cam slot engages or receives the force delivered by the The cross head 43 is carried upon a piston rod 44 operatively connected to a piston 45 working in a cylinder 46. The cross head 43 is guided in its movement by the slide 4? which is attached to the frame It upon a fixed pin 48. The motor cylinder 43 is mounted at its lower end upon a fixed pin 49 carried by a pedestal 50 secured to the frame l0. It will be noted that the motor cylinder 46 and the slide 4'! are rigid structures secured at both ends to the frame so that the motor or operating means is fixed in position and does not pivot. Motor springs 5! have one end thereof fastened to the ends of the roller shaft 42 and the other end secured to a lug 52 upon the base of the frame Ii).

The actuating means 35 moves in a path or direction of movement which is away from or at an angle to the path of movement of the roller 4! at least during the latter part of its movement. Because these parts of movement diverge during the power stroke, the roller 4| moves out of or away from engagement with the high speed portion 31 of the cam slot 38 and engages the camming portion 38 of the slot for a slower compression movement. It should be noted that so long as the roller 4| engages the end of the high speed portion of the cam slot 3'7, the actuating means 35 moves at or substantially at the same rate of speed as the roller. There is during this movement some mechanical ratio change taln'ng place as a consequence of a minor change in the radial distance between the roller and the pivot. This is wholly a radial change. When, however, the roller engages the cam slot or cam portion 38 then there is not only a more rapid mechanical ratio change of radial distance from the pivot 28, but there is also a camming action which is more important in converting a long piston stroke into a heavy compression stroke of the movable jaw.

An operating or press opening spring 54 is secured at one end to a projection 55 carried by the frame l8 and its other end is secured to a projection 56 carried by the jaw carrying member l4. This spring pulls upwardly on the jawcarrying member and swings it to open press position when the fluid pressure is released from the lower side of the piston 45 of the motor means. Fluid pressure applied to the piston 45 through the fluid supply line 58 closes the press which remains closed so long as the fluid pressure is applied to the piston. Upon exhausting the fluid pressure on the piston 45 the spring 54 opens the press. The spring and the motor means with its connections to the .cam means or slot 36 comprise the operating means for opening and closing the press. The roller 4% with the motor fluid supply pipe 58 by valve means known to the art, whereupon the piston 45 is forced upwardly and carrying the piston rod 44, the cross head 43 and the cam rollers 4| upwardly therewith. The cross head slide 41 and the rigid anchorage of the motor means to the frame brings about an upward straight line movement to the cam rollers 4|-as guided by the cross head 43 sliding in the straight cross head slide 41. Upward movement of'the cam rollers 4| swings the arms 35 or the cam means and the radius link means including radius links 25 and 21 in a counter-clockwise direction about the frame pivots 26 and 28 which swings the jaw-carrying member l4 upon the compound motion pivots 24 over the buck ,|2 the lower end of the jaw-carrying member being controlled in its means or guide pins |8 moving downwardly in the slots 20 until the press assumes the position shownin Figure 3. In this position the press head is at the end of the press closing movement and at the beginning of the movement which brings about jaw compression.

Continued upward movement of the cam rollers 4| brings the head l3 substantially vertically downward upon the buck |2 because the radius movement. Upon releasing the fluid pressure upon the piston 45, the piston springs 5| pull the piston 45 and cam roller 4| downwardly and the springs 54 pull thejaw-carrying member |4 upwardly-thereby opening the press.

It has previously-been mentioned that the portion 3'|-of the cam slot 3'6 is a high-speed portion and is so termed because it brings about a rapid and,- consequently, in open press position as shown in Figure 2 and in particular in Figure'5; with the cam rollers 4| at the end of the cam slot 36 nearest to the frame pivot 28, a small cam roller 4| upwardly will produce a relatively considerable rotation of the radius links 21 and a considerable movement 'of'the press head |3. It'will be clear, there fore, that as the cam roller-4| continues its upward movement and movesfarther along the high-speedportion 31 of 'the"cam slot 36 or farther away from the frame pivot 28, the cam means rotates-relatively less for a unit extent of movementof-thecam roller 4|" and the jaw-car- I4 will also move at a relatively the movement of rying member slower rate, yet

portion of the cam which may be expressed also as a lessening of the angle between the direction of movement of the cam roller ll or of the slide M during the compression movement of the head l3.

Amechanical advantage ratio changing means is therefore provided so that the first short portion of the stroke of the piston 15, say less than approximately half of the stroke, is utilized to close the press head through the operation of the cam way 3?, whereupon the angular portion 36 in the cam changes the ratio of the piston stroke to the press head travel, whereupon all the remaining portion of the piston stroke is utilized to move the head through the short distance required to compress the pad and work on the buck. This ratio changing means acts during the motor stroke to utilize a minimum portion of the stroke of the motor to close the press and save the major portion of the stroke to produce jaw compression,

The mounting of the jaw-carrying member M upon the frame Hi, as shown particularly in Figure 6, provides a plurality of horizontally spaced compound motion pivots 24 upon the jawcarrying member it3 l. A pair of spaced radius links 25 and 2'! are provided on either side of the bearings 23 so that the flanges 3! of the jawcarrying member swing between the pairs of spaced radius links 25 and Ti thereby producing a rigid and wobble-proof construction for the member. This construction also provides a three point frame mounting for the jaw-carrying member l4 upon the frame pivots '26 in the sides of the frame and on the frame pivot 28 carried by the central bearing 29, thereby setting up a plurality of frame pivots for the jaw-carrying member. A rigid mounting for the radius link means and consequently for the jaw-carrying member l4 results, which assists materially in reducing wobble or weaving between the jaws due to looseness o-r clearance in any of the bearings which support the jaw-carrying member. The flanges 3| carried by the jaw-carrying member l4 enable such three point suspension of the jaw-carrying member without sacrificing any of the rigidity of the member [4.

, The three point suspension or pivoting of the press frame l4, 3! shown in Figure 6 may have the radius links 25 and 21 anchored to each or any of the frame pivots 2t, 28 or to each compound motion pivot Z i by pinning, keying or any other method. With the radius links fixed to their pivots, the mounting for the jaw-carrying member i4, 35 is more rigid than any other and the various pivots 24, 26, 28 with the radius links 25 and 27 together form a crank shaft construction. The frame pivots 26, 28 may however, as an alternative construction be fixed to the frame and the compound motion pivots 2 be fixed to the hubs. or bearings 23 on the jaw-carrying member Hi, 3!. In this construction the radius links 25 and 21 are free to turn on the pivots.
